Like most digital signage applications of 3D, glasses-free was a must since it would be difficult or impossible to distribute the 100’s of thousands of pairs of glasses that would be needed for a glasses-based 3D display. A lot of people look at the Macy’s windows between when they were unveiled on November 11th and when they will be gone in January.
Shortly after Christmas last year 3DFusion invited Macy’s executives to their offices on Wall Street to see their large-screen, tiled autostereoscopic display technology. They must have liked what they saw because by May there was a project underway to produce a 3D window as part of the 2011 Macy’s holiday windows project."
..."The content was, of course, produced by Macy’s as 2D content. It was a 90-second loop of a spaceship on a star field. Presumably delivering wishes to children, since the windows all had a Make-a-Wish Foundation theme. The content was converted to autostereoscopic 3D by 3DFusion, using their proprietary plug-ins to Autodesk’s 3D Studio Max. Special plug-ins were developed for this project and ... the software people at 3DFusion worked 24/7 for a while to get this software to work right..."
